Method and material for the production of tooth restorations of tooth replacement parts

Abstract

In a method for the production of tooth restorations or tooth replacement parts from a non-metallic, inorganic material firstly a modelable material is modeled in plastic form in the mouth of a patient or with use of a model to a shaped part. The molding is then taken from the mouth of the patient or removed from the model and hardened to a ceramic tooth restoration or a tooth replacement part.

1 . Method for the production of tooth restorations or tooth replacement parts from a non-metallic, inorganic material, comprising the steps of 
 a) modeling a modelable material in plastic form in the mouth of a patient or with use of a model to form a shaped part;    b) removing the shaped part from the mouth of the patient or from the model; and    c) hardening the shaped part to a ceramic tooth restoration or to a tooth replacement part.    
   
   
       2 . The method of  claim 1 , comprising pre-hardening the modeled shaped part before removal from the mouth of the patient or from the model.  
   
   
       3 . The method of  claim 2 , comprising pre-hardening the shaped part by irradiating the shaped part.  
   
   
       4 . The method of  claim 2 , wherein the material contains a component through the effect of which the material has a higher stability with increasing time.  
   
   
       5 . The method of  claim 1 , wherein the modelable material does not shrink during the hardening step.  
   
   
       6 . The method of  claim 1 , wherein the modelable material shrinks by a desired amount during the hardening.  
   
   
       7 . The method of  claim 1 , removing comprising the shaped part from the mouth of the patient or from the model with the aid of an assisting element.  
   
   
       8 . The method of  claim 7 , wherein, 
 the assisting element is a pin or a projection provided on the shaped part.    
   
   
       9 . Material for the production of tooth restorations or tooth replacement parts, comprising 
 a ceramic component which makes possible a hardening of the material to a ceramic part, and    a binder which places the material in a plasticized state.    
   
   
       10 . Material of  claim 9 , wherein the binder makes possible a pre-hardening of a shaped part formed of the material.
